POEPPELMEIER, OF DAYTON, OI-IIO, {KSSIGNOB T SE'I -O-TY PE COMPANY, OF DAYTON, OHIO, A CORPQBATION OF OHIO TYPE LooKINee An Application filed October 27,

This invention relates to new and useful lmprovements 111 quads for fixing the position of type in the T-slots of chase plates lock them in a fixed position relative to a i predetermined marginal spacing.

This invention contemplates the use of a quad formed with a V-slot in its top portion to permit the two raised projections to be spread apart by a center punch after the 5 quad is placed in a desired position in the chase plate slot in front of, or behind, the type therein. When the two raised projections of the quad are thus spread apart, they will lockingly engage the topshoulders of the slot to hold it in a fixed position within the latter. 1

It is another object of my invention to make the locking quads of the same metal as that from which the type themselves have been cast. The quads, being cast from a softer metal than that from Which the chase plate is made, will not injure its type grooves. g

It is another object of my invention to provide a quad that will hold the type rigidly in place during the printing operation, but which may be easily dislodged from the chase plate without the use oftools when it is desired to discard the composition set-up.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawings illustrating my invention, Figure 1 is a perspective view of a portion of a chase plate, showing a locking quad in place at the end of one line and a similar locking quad in place in front of the type in another line. Figure 2 is a perspective view of a locking quad before it is used. Figure 3 is an end view of a looking quad, showing in dotted lines the V- shaped point of the punch in place for the locking operation. Figure 4 is an end view of a. locking quad in its locked position in a ect of my invention .quads at the rear of arow of type and-another quad at the front ofa second row of ashouldered member that is cast from a 1930. Serial No. 491,3s0i

T-slot er the chase, plate. And Figure 5 is a i sicleview of a conventional automatic center punch to perform the locking operation.

Referring to the accompanying drawings for a detaileddescription ofmy invention,

the numeralfl in Figure l designates a chase plate formed with T-slots 2 to recelve any shoulder type 3. i

7 After a row of selected type Shas been set within a T-slot 2, in a position to, conform to a predetermined marginal spacing, a locking quad 4 is insertedin the slot and moved into engagement with atype at the end of the row. in Figure 1 I have shown one of my type to illustrate how the quad may be used at either end ofa line of type to lock it in a predetermined position. Each locking quad 4 preferably consists of metal. which is softer than that from which the chase plate 1 is made, in order that the quad will not injure the grooves of the plate. Referring to Figures 1 and 2 for a'moreparticular description of this quad, itrwill be seen that the latter comprises a cast member of-T-shape having a'na'rrow base 5 and a wide "top 6 between which there are two side grooves 7, 7 to fit the shoulders 8, 8 that ill") define the top of each slot 2 in the chase plate.

Raised from the top of the quad are two pyramidal projections 9, 9 with a deep V- shaped slot 10 between them. The horizontal center line of the V-shaped slot of each quad 4 runs parallel with the slot whichreceives the quad in the chase plate or segment to permit it to be locked in the slot by the means now to be described.

After a line of type such as that which spells the name John Doe in Figure 1, is set in a slot 2, a quad is inserted in that slot and moved through it against the last type at the left end of that row. A conventional automatic center punch 11 carrying a V4195 will spread the portions 9, 9 of the quad at"? the side of the slot, into looking engagement with the shoulders 8, 8 of the slot 2 in the chase plate to hold the quad fixedly thereln. Being so held within the T-slot 2, the quad 5' will lock the row of type in that slot against movement into the marginal space beyond the quad, Thus it isv possible with myquaads 4 to look any row of type in any fixed posi tion within the chase plate or segment.

Having described my invention, I claim;

1. A locking quad insertible in at T-sl'ot of a chase plate or segment, in front of, or behind, a row of type therein, comprising a shouldered member to fit said slot and formed I in its top portion with a V-slot whose horizental-E center line is parallel with the-type -slot,'whereby the top parts of said member may be s-preadi apart into looking engagement with the shoulders'of the-T-sl-bt by w Wedge 3. locking quad insertible in a- T slot of a chase plate or segment, front of, or be- ':35 hind, a row oftypetherein, comprising a sh eu'ltlereel member cast from a softer metal than that-hem which the Chase pram orseg- 'mentie made; and formed in its top' portion with a deep V-sl'ot whose horizontal center :40 line-is parallelwith t'hetype'slot, and'shoulders at. the sides of the V-slot adapted to be forced intolocking engagement with the 'shoulders' oft'lie T slot by the V'-point of a Center punch inserted in the V-sl'ot of the e l r In testimony" whereof I have hereunto set my band this 25th day of October, 1930.
